Omnis in the house could leave misleading clues... But there are telltale signs, such as those below...- there are four different things floating in liquid in the fridge- the blender looks like it could chew through brick, and it could!- you find bulk quantities of nuts or unidentifed powders, often sealed with clothes pegs- something is soaking in a bowl covered in a cloth

Any more? Or is this just me?!

I was looking in my fridge earlier and thinking that, despite the ham (ick) it was a dead giveaway!

Gram flour- not conclusive but...Vital wheat gluten- pretty conclusive in the UK I think, where you have to order it and it costs a bloody fortune.Liquid smoke ditto- not conclusive on its own but if there's tamari in the fridge... Well'
